我们正在尝试将 SFTP 文件从大型机传输到新的 Linux 服务器。我们向目标服务器团队提供了我们的（大型机）公钥，他们配置了该公钥。发送文件时，我们收到以下错误：

我们如何解决这个问题？目前，一些 SFTP 运行良好多年，对于新的配置，我们面临这个问题。
答案1
您的密钥被拒绝可能是由于服务器端的文件权限错误。
debug1: Offering public key: /export/home/HEATFTP/.ssh/id_rsa
debug2: we sent a publickey packet, wait for reply
debug1: Authentications that can continue: publickey
debug2: we did not send a packet, disable method
debug1: No more authentication methods to try.
.ssh 文件夹以及 $HOME 目录 除所有者之外的任何人都不能读取。
